STREET-SPRINK'LER.

SPECIFICATION forming part of Letters Patent No. 784,297, dated March 7, 1905.

Application iiled September 6, 1904. Serial No. 223,545.

To @ZZ whom it may concern:

Be it known that IVILLIAM J. BoLE, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and uset'ul Improvements in Street-Sprinklers, of which the following is a specification.

My improvements relate to the construction and operation of a sprinkler-head and valve whereby the size and direction of the discharged stream may be readily controlled and the opening and closing of the valve made simple and effective and also means for governing' each of the above features by a single operating means.

The details of construction and further objects of my invention will appear more fully in the description and the claims hereinafter.

In-the drawings forming part of this specilication, Figure 1 is a perspective view of my improved sprinkler head and controlling means. Fig. Q is a cross-section through the sprinkler-head, showing the valve and taken on the line 2 2 of Fig. 3 looking in the direction of the arrows. Fig. 3 isa sectional view taken on the line 3 3 of Fig. 2 and showing the valve-casing. Figs. 4 and 5 are perspective views ot' the valve. Fig. 6 is an elevation of the valve-operating gear with the casing removed.

Similar numerals of reference designate corresponding parts throughout the various Views.

My improvements are adapted for use with any kind of a sprinkling car, wagon, o1' any other sprinkling means with which a stream of water is directed on the roadways, and I have therefore illustrated my improvements separate from the various parts of the vehicle on which it is carried.

The valve and sprinkler-head are adapted to be secured to any of the ordinary supplypipes, such as 1, which is fed from the tank in any desired way. At the end of the pipe I have secured a sprinkler-head and valve mechanism by a .suitable threaded stem 2, which may have a nut or packingjoint formed thereon to make the parts water-tight. fithin the sprinkler-head 3 is inclosed the operating-valve, which is secured to a spindle 4, extending outwardly through the casing, in which latter it has a bearing, and a suitable support 5, which acts as a bearing for the free end of the spindle, the bearing being secured to any part ot' the vehicle which would give it the proper position and relation to the spindie and valve.

The vertical shaft 6, which acts both as a lever and operating-shaft, is fulcrumed to a support '7, carried by the vehicle, so as to pivot from the joint 8, in which latter the shaft is also adapted to rotate. Any suitable guide means, such as the eye 9, may be attached to the dashboard lO of the car or in any desired place and is adapted to act as a guide for the upper end ot' the shaft. An angular handle l1 ot' any desired shape is attached to the upper' end ol the shaft for the purpose of moving it longitudinally and revolving. lPhe support 7, while it is not shown as attached to any part of the vehicle, it is understood may be attached to the platform of a car or otherwise suitably secured to the vehicle which it is adapted to be used upon.

In the exact construction which I have illustrated the sprinkler-head is provided with a substantially circular casing' 12, which I have provided with outwardly-extending flanges 13 to give strength and stability to the valvecasing. The interior ot' the casing is provided with a central bore 14, which is open at one end. The open end ot' the casing maybe closed by any suitable means, such as a head 15, secured t0 the casing by any mechanical means and provided with a packed joint 16, through which the spindle i passes and in which it is adapted to rotate and also for longitudinal movement. The interior bore 14C serves to contain a cylindrical operating-valve 17. This latter valve is s0 constructed as to govern the direction and size ofthe waterdischarge stream by one movement, while by a second movement it acts as a valve to immediately open or close the fiow of water. For this purpose I have Iliade the valve cylindrical and provided it with a dischargeopening 18 in its periphery, passing part way around it, the opening 18 communicating' with the interior space of the valve and is made to flare from the interior outwardly to correspond with the flaring opening 19 in the casing, whereby the stream will be fan-shaped or Haring. Preferably on the opposite side of the valve of the opening 18 are provided openings 20, which communicate with the supply-pipe and communicate with apertures 21 in the sides of the valve, which I preferably provide therein for the purpose of allowing the water to pass into .the space formed by the converging of the inner sides 22 of the valve, this space being lettered 23 in the drawings. This is not absolutely necessary, but very desirable for the purpose of equalization of pressure. The sides 22 of the valve converge toward the opening 18, so as to divert the Water to the opening as it enters through the ports 2O of the opposite side of the valve-casing. I preferably provide a triangular bridge 24 in the casing, so as to give an intermediate part 25 of the valve a proper bearing and also to divert the stream through vthe ports 2O and into the valve. As will be understood, the valve is adapted to revolve inside of the casing, and by making the bore of the casing of greater length than the valve the latter is adapted to have a longitudinal play in the casing for the purpose of sliding the valve so as to open and close the dischargeopening 19. rI`he movement of the valve longitudinally need only be sufcient to close the port 19. The purpose in rotating the valve is to make the opening 18 register with the opening 19 throughout its length and to govern the position of the opening so that the stream may be discharged either vertically or horizontally or may be discharged the entire length of the opening 19, as may be desired,

and is controlled by the handle 11 on the spindle, as will be seen from the hereinafter description of the gear.

In order to provide a means for shifting the spindle 4 with the lever 6 and to rotate same, I have provided a pair of miter-gears, one of which, 26, is secured to tlie end of the shaft 6 and the other, 27, is secured on the spindle 4, so that the two mesh at the point 28. For the purpose of connecting the shaft and spindle I have provided a bracket 29, the upper part 30 of which is journaled to the end of the shaft 6, and in the sides I have provided journals 31 and 32 for receiving the spindle 4. The opening's in the journal 31 and 32 are elongated slightly, so as to allow for the shifting of the spindle in the arc of the shaft 6 that is, the bracket 29 is adapted to move with the spindle 6-and by making the openings in the journal 31 and 32 elongated allowance is made for the slight circular movement of the bracket 29 in relation to the spindle 4. Any suitable casing 33 may be provided as a housing for the two gears and is preferably connected to the bracket 29.

The operation of my invention will be readily understood from the description of the construction thereof. When it is desired to open the valve, the lever 6 is thrust longitudinally, so that the opening 18 registers with the opening 19,whereupon the liow of water may pass through both. When it is desired to regulate the opening 19 so as to increase or decrease or change the direction of' the stream, the handle 11 of the spindle is revolved, thereby causing the gear 26 to rotate the gear 27, and thus the spindle 4, which transmits the motion to the valve and causes the latter to rotate in either direction, whereby the water may be made to pass out at any part of the opening 19.

While many changes may be made in the construction of my new sprinkler-head without departing from the spirit of my invention, I do not desire to be understood as limiting the scope of the annexed claims by describing in details the exact construction which I have used. l
